  • the device 10 has two groups of inclined platforms shown at 12a, 12b, 12c, 12d and the second group shown at 14a, 14b, 14c and 14d. It can be seen that the platforms 12 are nested between the platforms 14 between the two locations A and B.
  • each of the platforms has an upper log-receiving surface 16 and a leading edge region 18 adjacent said upper log-receiving surface.
  • the leading edge region on a platform of the first group travels along the log-receiving surface of a lower platform of the second group in a reciprocal fashion as shown by the arrow 'C between two limits, a lower limit being shown in dashed lines where the leading edge region, for example of the platform 12a is generally aligned with the leading edge region of the upper platform 14a, and an upper limit shown in chain dotted lines where the leading edge region of the platform 12a is generally aligned with the lower platform 14b.

  • the upper and lower limits are reached when the leading edge regions of the respective platforms are generally aligned with one another.
  • the device may in some cases function to transfer the article from one article-receiving surface to another, without having the leading edge regions generally aligned as in this case.
  • other arrangements may provide the leading edge regions to be within a fraction of an inch or greater to a number of inches.
  • leading edge regions need to be close or aligned will depend on the dimensions of the article being transferred. For example, a relatively large article such as a log, may be successfully transferred in all cases when the leading edge regions are within an inch or so of alignment, whereas a smaller article may need closer alignment of the leading edge regions to achieve successful transfer. Desirably, the alignment of the leading edge regions in this particular case, should allow for substantially all of the log debris and the like to be transferred from the article-receiving surface to another in order to reduce its buildup.
  • drive means is also provided at 19 for driving the first and second groups in a reciprocal motion along parallel axes as shown at Al and A2, wherein the first group of platforms is displaced in an opposite manner to the second group.
  • the drive means is operable to displace a selected platform in the above mentioned reciprocal motion between the upper limit.
  • Each of the first group of platforms 12 are mounted on a first drive frame member 20 while each of the second group of platforms 14 are mounted on a second drive frame member 22.

  • the drive link 38 is pivoted, at its opposite end, to a drive motor 40.
  • the drive means may also include other aspects of the drive disclosed in the Applicant's above mentioned PCT application.
  • the leading edge region of the selected platform is operable to displace logs along the next lower platform, thereby to transfer logs from one platform to another as the platforms move in the reciprocal motion.
  • each of the leading edge regions includes an end face 18a which is generally perpendicular to the log-receiving surface.
  • the end face is generally planar.
  • the platforms 12 and 14 are sufficiently close to one another that, in addition to transferring logs from one platform to the next, the reciprocating platforms are capable of transferring debris from one platform to the next, thereby making the task of cleaning a less frequent necessity.
  • the edge face may also be provided with a resilient seal shown at 18b along its lower edge, for example of suitable plastics such as that sold under the trade name TEFLON for establishing a relatively low friction sliding relationship there between.
  • leading edge region and the platforms themselves can take a number of different forms.

  • the upper log-receiving surface of the platform may also be non-planar as shown in figures 5, 6 and 8e to 8h.
  • the platforms may have an angular cross section or a sinusoidal cross section.
  • These log-receiving surfaces may be beneficial, in some cases, because they provide a number of contact regions PI, P2 and P3 with the log which provides a more controlled engagement of the log with the platform, by reducing the chances that the log will teeter, roll or shift as it travels with the platform, to the extent that it slips off the leading edge region.
  • the leading edge region when saw toothed , provides a similar benefit in providing a number of contact regions for improved contact with the log.
  • the angular log-receiving surface and the saw-tooth profiled leading edge region should provide for improved transfer of both the logs between locations A and B and the log debris.

Abstract

L'invention concerne un dispositif (10) pour le transfert d'articles entre deux emplacements espacés (A, B), qui comporte deux groupes (12a, 12b, 12c, 12d; 14a, 14b, 14c, 14d) de plates-formes inclinées comportant chacune une surface supérieure (16) de réception d'articles et une zone de bord avançant (18). Ainsi, chaque surface de réception d'articles du premier groupe est chevauchée par une plate-forme du second groupe. Le dispositif peut assurer l'alternance de positionnement de chacune des plates-formes du premier groupe par rapport à une seconde plate-forme correspondante, entre deux positions, moyennant quoi la zone de bord avançant de chacune des plates-formes du premier groupe est alignée avec une zone de bord avançant correspondante d'une plate-forme du second groupe.
